WRAPPER-ORWEB FEEDING IVIECHANISM.

Original application filed May 14, 1820,-Serial No. 381,453. Divided and this a1'1p1ication'fi1ed {November Serial 1104601,?85. v

This invention relates to a wrapper or web feeding mechanism for candy wrapping ma chines, in which the wrapper is intermittently fed forward through a pairof co-operating feed rolls to a chute or platform over whichthe sti'cksof candy are caused to pass as they are fed into the machine.

This application is a division of my copending application Serial No. 381,453, filed May 14th, 1920.

It is an object of this invention to provide a novel, simple andimproved wrapper feeding mechanism that is intermittently operated for feeding a predetermined strip of paper from a vreel for wrapping a stick of candy.

This invention comprises the novel mecha-,

nisms and combinations hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings, which illustrate a preferred embodiment of this invention, and in which similar reference numerals rcferto similar featuresin the different views:

Figure 1 is an elevational view ofabracket or frame member that supports the paper feeding mechanism and that forms part of the. candy wrapping machine disclosed in my aforementioned application.

Figure 2 is a sectional view through a part of said machine illustrating the driving HIGCIIEIHlSDIfOT the paper feeding mechanism in elevation. I

Figure 3 is an enlargedtransverse section through the paper feeding-rolls showing the bracket in elevation.

Figure 4 is an enlarged longitudinal section through the paper feeding mechanism.

Figure 5 is an elevational View of the roller clutch member.

As shown on the drawings:

In referring now to the drawings, the reference numeral 1 indicates a frame or bracket having an upper bracket member 1 secured or pivoted thereto. These brackets form part of the candy wrapping machine illustrated in my copending application. A reel 2 is rotatably supported in the frame 1 and the paper 2 which forms the wrapper, and which is commonly called the web, for wrapping the candy is led therefrom over a guide roll 3 supported on an arm 4: eX- tending from the frame. From the guide ably supported in the top bracket 1 and from the guide roll 9, the paper .web is passed between the feedrollslO and 11.

In referring to Fig. 4,.it will be observed that the feed rolls are provided with circular grooves 12 wiereby the peripheries are divided into spaced contacting portions. The spaced contactingportion 13at one end of the roll is adapted to be moistened by a rotary moistening element 1 1 ,rotatably mounted in a fluid container 15 andpr ojecting through a slot in the bottom thereof. Bars 16 and17 are supported with theirends within the grooves 12, as shown in Fig. These bars serve as strippers to preventithe paper web from being wound around ,the rolls andtheyalso serve as aguideway for the web.

The roll 10 is provided with end journals which are rotatably mounted in bearing blocks 18 which aresupported in 'guideways or boxes in the frame 1. The upperendsof these blocks are provided with hearing recesses for receiving the ends of the spindle 18 thatv extends through thefluid container and that has the moistening element 14; keyed .orsecured thereon andthat supports the fluid container. A gear 19 is secured upon the spindle 18and this gear is driven by a gear 20 securedto the hub of the roll 10. The gear 20 is in turn driven by a gear 21 secured upon the hub 22 of the lower feed roll 11.

The hub 22 of roller 11 is illustrated as provided with an annular flange or abutment 22 upon which the gear 21 is secured, the web of the roll 11 being clamped against said flange by a nut 23 adjustably threaded upon the hub. The adjacent end of the hub 22 is rotatably journalled in a bearing formed in the casing 1 The front or righthand end of said hub is provided with a clutch face, as shown more clearly in 5. This clutch face is provided with two opposite slopes or cam surfaces that terminate in diametrically opposite shoulders 24 which are adapted to be engaged by two diametriice cally opposite spring-pressed plungers slidingly supported in suitable bores in a head 26 keyed upon one end of a shaft 27 loosely extending through the hub 22 and journalled at its other end in a bearing formed in the bracket 1 It will be ap parent that as the shaft 27 is rotated in one direction, in an anti-clockwise direction in the present instance, the inner ends of the plungers 25 will engage the shoulders 2L and rotate the roll 11 in one direction, and that when the shaft 27 is rotated in the opposite direction, the plungers 25 will ride up the cam surfaces and out of engagement with said shoulders, and as long as the shaft 27 rotates in this opposite direction there will be no rotation imparted to the roll 11. The shaft 27 may therefore be said to be connected to the roll 11 through a uni-directional clutch.

The end of the shaft 27 opposite the head 26 extends through the bracket 1" where it has a pinion 28-keyed thereon whereby the said shaft may be rotated. Mechanism has been provided for alternately rotating the shaft 27 in opposite directions, and in the form shown this mechanism consists of a spirally grooved cam 29 (Fig. secured upon the driven shaft 30 which is driven in a suitable manner by a motor or the like. A roller 31 is positioned within the cam groove, and supported upon an arm extending from a bearing sleeve 33 journalled upon a short shaft 34 suitably supported by the frame of the machine. A link 36 connect-s the arm 32 with a second arm 37 extending from a sleeve38 journalled upon a stub shaft 39 suitably journalled in the frame-work of the machine.

The end of the arm 37 is provided with a segment gear or rack 40 (Fig. i) that meshes with the pinion 28 on the shaft 27. It Will be apparent that rotation of the cam 29 will oscillate the arm 32 backwards and forwards imparting a similar movement to the segment arm 37 connected thereto by the link 36, and as the arm 37 is oscillated baclo ward and forward, it will oscillate the shaft 27 which, during an anti-clockwise rotation, will rotate the roll 11 and through gears 21 and 20 will rolate the roll 10, and through the gears 20 and 19 the moistening element 1 will be oscillated. As the shaft 27 is oscillated in a clockwise direction, the rolls and moistening element will remain idle on account of the unidirectional clutch, as previously explained.

From the foregoing it will be obvious that an etiicient and simple web feeding mechanism for a candy wrapping machine has been provided in which the liability of the wrapping paper winding around the rolls is avoided, and in which the wrapping paper is interi'nittei'itly fed forward by an alternately rotatable shaft and in which the wrapping paper or web is evenly advanced.

I am aware that numerous details of construction may be varied through a wide range without departing from the principlea of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

l claim as my invention:

1. In a candy wrapping machine, a pair of iniergeared web feeding rolls, one of said rolls being provided with a hub having a uni-directional clutch face upon one end, a bearing in which one end of said hub is ournalled, a shaftloosely eJ-Itending tl'irough said hub, a head keyed upon said shaft. spring-pressed plungers carried by said head and adapted for clutching engagement with said hub during one direction of rotation of said shaft, and means for oscillating said shaft.

2. In a candy wrapping machine, a pair of intergeared web feeding rolls, one of said rolls having an end in the form of a unidirectional clutch, a shaft loosely extending through the last mentioned roll, a head secured upon said shaft, and plunger-s yield ingly mounted in said head for coactiou with said clutch face.

In testimony whereof I have hereunfo subscribed my name.
